Add-in custom editor extension does not show in the toolbar

[JoseSanchez]

Hello everyone,

I am working on an AddIn in Vb.net using the sample "AddInEditorExtension" as a template and now that I finished it I do into see in ArcMap in the toolbar or in ArcMap Extensions list the name of the Add-In.

I would like to know how a user can enable or disable the AddInextension.

Where can I find the name of this AddIn other than in the Add-In list.

Thank you

Depending on the type of functionality you have built you may need to register the component.

Many of these customizations can be built and deployed as add-ins, while others require development of custom components...

The following table shows the various editor customization types and their supported customization methods:

Customization type	Add-in	Component
Commands	Yes	Yes
Context menus	Yes	Yes
Tools	Yes	Yes
Construction tools	Yes	Yes
Extensions	Yes	Yes
Shape constructors	No	Yes
Tasks	No	Yes
Object inspectors	No	Yes
Snap agents	No	Yes
Edit sketch extensions	No	Yes

Custom components require the old style COM registration before ArcGIS will load them.

There is more information in the help in the Extending ArcObjects section:

Have you tried hooking into the extension and setting its state?

You can get the guid for the extension by calling ThisAddIn.IDs.<NameOfYourExtensionClass> within the addin code where the extension lives.

Hi,

I am using the same functionality that comes on this project. Please feel free to download it to take a closer look.

it does not need to be registered.

Editor extensions will not display in the Extensions list of ArcMap. For example, the Editor in ArcMap is actually an extension named "Esri Object Editor". If you open the Extensions dialog you'll see that this name doesn't appear there. An editor extension essentially hooks into this extension to enable/disable itself.

I would suggest two workflows if you're needing to be able to turn this extension on/off.

1. Use a regular Extension instead of an Editor Extension. Both are implemented in the same manner (i.e. when the application or editor starts you wire your code into events where you need to implement your logic). With the regular Extension you'd be able to expose your custom extension in the ExtensionDialog. This would allow users to be able to enable/disable your extension from the ArcMap UI. You could also use the link I posted before to automate this process by wiring into other events throughout the system.

2. Use an Editor Extension. This extension will be treated as a JIT extension. You'd need to cycle through the JITExtensionManager to hook into your edit extension. Once you've located it you could call its  OnStartup or OnShutdown methods to essentially turn your logic on or off.

I only had a few minutes to write this up...so below is what I was able to create and test. This appears to be working for me so far. You'd need to implement the logic to control when to call Startup or Shutdown and you'd also need to setup the needed wiring within both of these methods.
